From the 1980s small surface mount parts have been used increasingly instead of through-hole components; this has led to smaller boards for a given functionality and lower production costs, but with some additional difficulty in servicing faulty boards.

Historically many measurements related to PCB design were specified in multiples of a thousandth of an inch, often called "mils". For example, DIP and most other through-hole components have pins located on a grid spacing of 100 mils, in order to be breadboard-friendly. Surface-mount SOIC components have a pin pitch of 50 mils. SOP components have a pin pitch of 25 mils. Level B technology recommends a minimum trace width of 8 mils, which allows "double-track" – two traces between DIP pins.

Company Profile

We know almost all electronic engineers got a problem to found a right manufacturer to make PCB prototypes & small batch order because big factories don't want to make small orders, they always gave high price and very long delivery time, they can't provide fast delivery service. The small factories gave low price, but their quality control and service/English communication are not good, they can't meet customer’s request also. This is why we made JETEK and we are committed to make JETEK become a professional PCB supplier with rapid response、sincere service、excellent quality and reasonable price. Of course we also accept high volume PCB order.

JETEK’s engineers and workers are most have many years working experience, we supply our products all around the world. We have perfect processes to allow you to get the high quality PCB with door to door service with fastest turnaround, all of our PCBs approved by ISO9001/TS16949 and UL certificate.

Our Vision is to help people around the world to get high quality PCBs on an Easy & safely way.
